As temperatures rise, flowers, grasses, and trees begin to sprout new branches and buds. Various pests and diseases emerge from hibernation and enter the early incubation period of eggs and larvae. Taking preventative measures and timely treatment can significantly reduce the number of pests and diseases throughout the year, ensuring vigorous plant growth.     

       Also known as aphids, their main hosts include large-leaved boxwood, red-leaved plum, peach, crabapple, firethorn, crape myrtle, rose, oleander, and so on. Their damage not only causes leaf shrinkage and poor growth, but the honeydew secreted by aphids can also induce sooty mold and viral diseases.

　　Prevention and control measures:

　　Long-lasting root irrigation control: Before the occurrence of pests in early spring, irrigate the roots with "Root Irrigation Aphid Killer" or "Insecticide Fertilizer" to prevent various aphids for up to a year, protecting the trees from pests throughout the year; if pesticides are applied when pests occur, they will kill the pests and control them for a long time, protecting the trees from subsequent pests.

　　Spraying control: Spraying with a 1000-1500 times dilution of "Aphid Killer" can effectively control the occurrence and damage of aphids.

       The boxwood leafminer overwinters as a larva. As the weather warms, this insect will damage hedge plants such as boxwood, holly, and euonymus, severely affecting the growth of new shoots and even causing death. Control measures should be implemented as soon as damage is observed, especially in areas where the previous year's infestation was severe.

　　Prevention and control measures:

　　Long-lasting root irrigation for pest control: Watering the roots with "One-Drenching Tree Pest Killer" before the occurrence of pests in early spring can effectively prevent the occurrence of pests and provide protection for plants for several months.

　　Spraying control: Spray with "Moth Moth Killer" or "Chujing" at a dilution of 600-800 times to quickly eliminate pests.

       This insect mainly damages large-leaved boxwoods. It has a large appetite and likes to congregate to cause damage. It can be controlled by pesticides used to control the boxwood leafminer.

       Scale insects such as the Japanese wax scale, mulberry scale, ball scale, cottony cushion scale, and crape myrtle scale begin to cause damage from early to mid-March. They mainly damage the leaves, branches, and fruits of flowering trees and plants, sucking their sap and causing yellowing, deformities, and poor growth. Scale insect control should be carried out early; the earlier the control, the better the effect.

       Prevention and control measures:

　　Long-term prevention and control through root irrigation: Before the occurrence of pests in early spring, irrigate the roots with "Root Irrigation Scale Insect Killer" or "Insecticide Fertilizer" to prevent the occurrence of pests for a long time; if pesticides are applied when pests occur, the pesticides will be killed and stored in the tree, protecting the tree from subsequent pests.

　　Spraying control: Spray "Scale Insecticide" at a dilution of 600 times evenly, ensuring thorough coverage without dripping water, for ideal results.

       Red spider mites are widely distributed and are a major pest of garden flowers and trees, specifically damaging the leaves, stems, and flowers of plants. They reproduce rapidly, with a generation occurring in as little as five days, adding to the difficulty of control efforts.

       Prevention and control measures:

　　Long-lasting root irrigation control: Before the occurrence of pests in early spring, irrigate the roots with "Root Irrigation Aphid and Mite Killer" or "Insecticide and Fertilizer" to prevent the occurrence of various mites for a long time; if pests have already occurred, irrigate the roots in time to kill and control the pests. One application can effectively control the pests for several months, avoiding repeated spraying during the peak pest season, saving labor, time and effort.

　　Spray control: Spray "Spider Mite Killer" at a dilution of 1000-2000 times evenly. It is unaffected by high or low temperatures and is highly effective against resistant mites.

       White grubs overwinter in the soil. As the soil temperature rises, the grubs become active, feeding on and damaging seeds, seedlings, and roots, leading to poor growth of seedlings and lawns. In severe cases, large areas of turf are torn up and die.

　　Prevention and control measures:

       Apply the pesticide fertilizer "Shichongmin" or "Dichongjing" granules directly to the soil near the roots of lawns and seedlings, and water immediately after application to ensure the pesticide solution is fully dissolved into the active layer of pests.

      Powdery mildew affects a variety of garden plants, including roses, photins, large-leaved boxwoods, impatiens, smoke trees, narrow-leaved magnolias, and lawns. It inhibits photosynthesis and weakens plant growth. Affected plants typically have a white powdery coating on their leaves, and sometimes small black spots appear on the affected areas later, impacting flowering and growth, reducing ornamental value, and in severe cases, even causing plant death.

　　Prevention and control measures:

　　1. In early spring, strengthen pruning, remove diseased branches and leaves, and burn them in time; increase ventilation and light penetration between plants, and spray with 2000 times diluted leaf disease control solution before the plants sprout to prevent leaf diseases.

　　2. After the onset of the disease, spray with a systemic fungicide. Powdery mildew is a highly effective agent for treating powdery mildew. Dilute it 1500 times and spray it evenly on the leaves 1-2 times to eradicate the disease.

       Gummosis is the most important branch and trunk disease of trees, and it usually begins to appear in late March each year. It mainly affects fruit trees such as peach, apricot, plum, and sweet cherry. Once a tree is infected with this disease, it will start to exude gum, causing the tree to gradually weaken and even die.

　　Prevention and control measures:

　　Long-term prevention and control through root irrigation: Applying "Jian'an" fertilizer and pesticide to the roots replenishes nutrients, strengthens the tree, and provides long-term prevention and control of branch and trunk diseases such as gummosis.

　　Chemical control: In the early stages of the disease, spray the affected areas with a 100-200 times dilution of a fungicide to effectively kill the pathogens and quickly treat gummosis. If the disease is severe, first remove the gum, then apply a 30-50 times dilution of a fungicide to the affected area with a brush. One to two applications should result in a complete cure.

       Damping-off is the most common and serious disease in nurseries. It primarily affects coniferous seedlings of the genera *Cephalotaxus*, *Pinus*, and *Larix*, but also damages various broadleaf seedlings and ornamental flowering plants. Damping-off is highly susceptible to occur when soil moisture is high.

　　Prevention and control measures:

　　1. Strengthen nursery management: Level the land, prevent waterlogging, and ensure good soil aeration; avoid continuous cropping, and do not use nursery sites for crops that are susceptible to disease in the previous stage; control irrigation after sowing, etc.

　　2. Soil disinfection: Spray the seedbed with a 300-500 times diluted solution of the pesticide and fertilizer "Jian'an" to prevent soil-borne diseases such as damping-off and seedling blight, promote root growth and strong seedlings, and provide protection for seedlings for several months. The synergistic effect of the pesticide and fertilizer ensures the healthy growth of seedlings.
